And The World Shall Wait For Me Theory

I would like to take a moment to express my frustration with people (I'll take as many moments to do so as I please, this is just one of them). I'm sick of waiting in line at the grocery store while the lady in front of me writes a damn check! Reason 1. Checks are a thing of the past, get over it lady. Debit/Credit cards are loved by many for many reasons, mainly convenience. How does this concept not register with you? 2. If you MUST annoy everyone by writing a check, why must you wait until the full cart of groceries is scanned and totalled? You certainly must know that a total is coming, and that you are in need of payment for said total, why not have everything but the total written in while you are waiting, or does staring at the girl scanning the items amuse you that much. It's great watching you look surprised after the girl tells you the total, like you really thought all those items were going to miraculously sum up to zero. You then fumble through your purse to find your checkbook and then take your sweet ass time filling in the lines. Really, I really enjoy that.
I feel that this is the same lady that stands in front of me, contemplating for minutes which soda she'll decide to fill her cup up with, leaving no room for me to even fill my ice up, so as to at least somewhat appease me while I wait for she who has all the time in the world. She chose to come to the local maverik/7-11/wherever to get a drink, she certainly must have SOME idea of what it is she wanted..............guess not.
True, I am rarely in so much of a hurry that these people actually cause damage to my plans, but it's just the damn annoyance of it. I've decided it's just yet another reason that each person thinks he or she is the most important damn thing in the world.
